A subway pass as a starting value of $75. After one ride, the value of the pass is $72.50. After two rides, it's value is $70. After three rides, it's value is $67.50. Write an explicit formula to represent the remaining value on the card as an arithmetic sequence. What is the value of the pass after 15 rides? $40....$42.50...$2.50...$37.50
